DETAILED DESCRIPTION

Certain aspects and examples of the present disclosure relate to generating electronic documents from receipt content of an electronic mail (“email”) message and linking the electronic documents to secure records in a secure database corresponding to a transaction. The electronic documents may be viewable by an account holder from a secure network platform displaying the secure records for transactions between the account holder and third parties using an account. In some aspects, the electronic documents including the receipt content may be automatically linked to a secure record in the secure database using the metadata or description transmitted with the electronic receipt. For example, an email message including electronic receipt content may include “From” metadata having the email address from which the electronic receipt was sent and “Timestamp” metadata indicating when the email having the electronic receipt was sent by the retailer. The “From” metadata may be used to determine a retailer for a transaction associated with the electronic receipt. The electronic receipt system according to some aspects may link the electronic document (including the receipt content) to a secure record stored in the database by matching the metadata with a secure record corresponding to a transaction involving the same retailer indicated by the “From” metadata and occurring at or about the same time as the time indicated by the “Timestamp” metadata. When the account holder is authenticated to view the transaction record, details from the transaction record may be displayed, including a hyperlink or other access point for accessing the electronic document linked to the transaction record.

In some aspects, the account holder may be assigned a unique email address for receiving electronic receipts for purchases made by the account holder from third parties, including various retailers. The email address may include a local part corresponding to the account holder and a domain part corresponding to an entity managing the account and electronic receipt system. An electronic mail (“email”) message having an electronic receipt for the purchase may be transmitted to and stored in a common inbox associated with the account-managing entity. A system according to some aspects may capture the email message from the common inbox, extract metadata and receipt content from the email message, and convert the receipt content to an electronic document, such as a portable document format (“PDF”) document. The system may use the metadata from the email message to identify and link the electronic document with a secure record stored in a secure database corresponding to a transaction associated with the electronic receipt.

In some aspects, a user device may include a client-side engine in memory that may launch a device application for receiving images of receipts. The client-side engine may cause the user device to launch a recording device, such as a camera, of the user device to capture an image of a receipt corresponding to a transaction and to transmit the image with a description of the receipt to the system. The system may receive the image, extract the description as metadata, and convert the image into an electronic document that may be linked to a secure record of the transaction in the database. In some aspects, the system may further authenticate the account holder to access a network platform in which the account holder may view the secure record of the transaction and the electronic document linked to the secure record. Detailed descriptions of certain examples are discussed below. These illustrative examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts. The following sections describe various additional aspects and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions are used to describe the illustrative examples but, like the illustrative examples, should not be used to limit the present disclosure. The various figures described below depict examples of implementations for the present disclosure, but should not be used to limit the present disclosure.

Various aspects of the present disclosure may be implemented in various environments. For example, FIG. 1 is a block diagram depicting a network environment 100 including an electronic receipt system 102 according to some aspects of the present disclosure. The electronic receipt system 102 includes one or more server devices for linking electronic receipts to secure records corresponding to transactions associated an account held by an account holder. The electronic receipt may include receipt content that describes the details of a transaction between the account holder and a third party performed using money from the account. In some aspects, the electronic receipt system 102 may generate electronic documents including the receipt content. The electronic receipt system 102 may identify the transaction record corresponding to the transaction described in the receipt content and may link the electronic document to the transaction record. The electronic receipt system 102 may include a secure database 104 in which the transaction records are stored.

The secure database 104 may be a secure location in the electronic receipt system 102. The transaction records stored in the secure database 104 may be accessible to the account holder only subsequent to the account holder being authenticated by the electronic receipt system 102. In some aspects, subsequent to authenticating the account holder, the electronic receipt system 102 may generate one or a series of user interfaces displayable to the account holder and including the transaction records and the corresponding electronic documents including the receipt content associated with the transaction. In some aspects, the account holder may access the electronic receipt system 102 from a user device 106 to view the transaction records. The user device 106 may be a computing device, such as a personal computer, smartphone, personal digital assistant (“PDA”), tablet, or other device. The user device 106 may be communicatively coupled to the electronic receipt system 102 via a network 108, such as the Internet.

In some aspects, the electronic receipt system 102 may receive an electronic receipt associated with a transaction from an email system 110. The email system 110 may be accessible to the network 108 and may receive email messages including electronic receipts. The electronic receipt system 102 may generate an email address for the account holder that may be used by the account holder or third parties to transmit email messages including electronic receipts to the email system 110. The email address generated by the electronic receipt system 102 may include a local part and a domain part. For example, the electronic receipt system 102 may generate the email address “john.doe@bank.com,” where “john.doe” is the local part of email address and “bank.com” is the domain part of the email address. In some aspects, the local part of the email address may correspond to a username selected by the account holder and associating the email address with the account holder in the secure database 104. The email system 110 may include a common inbox 112 for storing email messages received by the email system 110. Email messages transmitted to an email address having the same domain part (e.g., “bank.com”) may be routed by the email system 110 to the common inbox 112.

In some aspects, the email message including the electronic receipt may be transmitted to the email system by a retailer 114. The retailer 114 may be a third party, such as a merchant, service provider, entity, or individual involved in the transaction with the account holder. For example, the account holder may purchase goods or services from the retailer 114 and the retailer 114 may generate an electronic receipt documenting the payment transaction for the goods or services. The account holder may provide the retailer 114 with the email address generated by the electronic receipt system 102 and may transmit an electronic copy of the receipt to the email address provided by the account holder.

The electronic receipt system 102 may retrieve the email message from the common inbox 112 and may associate them with the account holder using the local part of the email address (e.g., “john.doe”). The electronic receipt system 102 may be communicatively coupled to the email system 110 via the network 108. Although the email system 110 is shown in FIG. 1 as a separate system from the electronic receipt system 102, the email system 110 may alternatively be a subsystem of the electronic receipt system 102 without departing from the scope of the present disclosure. Similarly, the electronic receipt system 102 and the email system 110 may be communicatively coupled through a network separate from the network 108 or through a bus. The electronic receipt system 102 may associate the email including the electronic receipt with the account holder based on the local part of the email address, which may correspond to a username of the account holder.

In additional and alternative aspects, the electronic receipt system 102 may receive an electronic receipt directly from the account holder via the user device 106. In some aspects, the user device 106 may launch a client-side application that may allow the account holder to upload a receipt image captured by a camera of the user device 106 or retrieved from a storage device of the user device. For example, the client-side application may allow the account holder to take a picture of a paper receipt corresponding to a transaction between the account holder and the retailer 114. The account holder may transmit the receipt image to the electronic receipt system 102 from the user device 106 via the network 108. The client-side application may also allow the account holder to input a description of the receipt that may be transmitted to the electronic receipt system 102 with the receipt image.

FIG. 2 is a block diagram depicting memory locations in the electronic receipt system's 100 secure database 104 according to aspects of the present disclosure. The secure database 104 may associate information within each location to link electronic documents including electronic receipt content to an appropriate account holder. The secure database 104 may also use the associations to allow an account holder, subsequent to authentication by the electronic receipt system 102, to view electronic documents having information corresponding to a secure record stored in the secure database 104 from a user device via the network 108 of FIG. 1. In some aspects, the information may be associated in one or more indices in the secure database 104. For example, an index may include one or more columns, each including information that is associated with additional information in the same column of the index. In additional and alternative aspects, the information may be associated using pointers, objects, or other means for associating related information in the secure database 104. The information stored in the secure database 104 may be separated or partitioned by information type to allow the electronic receipt system 102 to query information based on the type. In some aspects, the association between the information stored in the secure database 104 may allow the electronic receipt system 102 to query information based on one type and use the associations to determine information of another type that is associated with the queried information.

Holder identifiers 200 are stored in the secure database 104 and include information corresponding to an identity of the account holders of the electronic receipt system 102. In some aspects, the holder identifiers 200 may include a unique set of alphanumeric characters, such as an online banking (“OLB”) number assigned to each account holder by the electronic receipt system 102 to distinguish each account holder from the others. In other aspects, the holder identifier 200 may include a unique set of alphanumeric characters provided by or issued to each account holder, such as, but not limited to a social security number or driver's license number. The holder identifier 200 for each account holder may be used to associate account information 202, authentication information 204, and email identifiers 206 with the account holder as represented by the arrows in FIG. 2.

The account information 202 may include information corresponding to one or more accounts held by each account holder. Examples of information that may be included as account information 202 may include an account number or a routing number associated with the account. The account information 202 may be associated with a holder identifier 200 corresponding to the account holder. The authentication information 204 may include information that may be used to authenticate the account holder to view secure records stored in the secure database 104. In some aspects, the authentication information 204 may include information provided by the account holder, such as, but not limited to, a username, password, social security number, passcode, or other authenticating information. In other aspects, the authentication information 204 may include information provided to the account holder, such as a personal identification number (“PIN”). The authentication information 204 may be stored in the secure database 104 and compared with input from the account holder via a user device (e.g., user device 106 of FIG. 1) for a match to conclude that the account holder is authorized to view the account information. In some aspects, the account information 202 may be accessed using the authentication information 204. For example, subsequent to the electronic receipt system 102 authenticating the account holder, the association between the authentication information 204 and the holder identifier 200 and the association between the holder identifier 200 and the account information 202 may be used to identify account information 202 corresponding to the authenticated account holder. The email identifiers 206 may include information corresponding to an email address generated by the electronic receipt system 102 that may be used to transmit electronic receipts to the system 102. In some examples, the email identifiers 206 may include a username that may be used as the local part of an email address assigned to the user. The email address may be used by third parties to transmit electronic receipts to the electronic receipt system 102.

The secure database 104 also includes transaction information 208. The transaction information 208 may include secure records corresponding to transactions between account holders and third parties for accounts corresponding to the account information 202. The transaction information 208 is associated with the account information 202 to allow the electronic receipt system 102 to determine to which account each secure record belongs. An email records list 210 may include email records corresponding to the email messages including electronic receipts that are received by the electronic receipt system 102 from the common inbox 112 of FIG. 1. The email records in the email records list 210 are associated with the account information 202, the email identifiers 206, and the transaction information 208. The email records in the email records list 210 may be associated with the account information 202 to allow email records not automatically matched to a secure record of the transaction information 208 to be accessible to the account holder for manually matching. The email records in the email records list 210 may be associated with the transaction information 208 to allow the account holder to view email records in the email records list 210 previously matched to a secure record of the transaction information 208. The email records in the email records list 210 may be associated with the email identifiers 206 to allow the electronic receipt system 102 to determine the email record associated with a particular account holder subsequent to retrieving the email messages from the common inbox 112 of FIG. 1. For example, the electronic receipt system 102 may retrieve an email message from the common inbox 112 and use the username stored as an email identifier 206 in the secure database 104 to generate an email record and associate the email record with the account holder using the username.

The electronic documents 212 may include electronic documents generated by the electronic receipt system 102 and including receipt content extracted from the email messages retrieved by the electronic receipt system 102 from the common inbox 112 of FIG. 1. The electronic documents 212 may be associated with the transaction information 208 to allow an electronic receipt having receipt content corresponding to a transaction to be viewed by the account holder from a user interface including information from the secure record of the transaction information 208 corresponding to the transaction. The electronic documents 212 may also be associated with the email record to allow the electronic documents 212 to be viewed by the account holder from a user interface displaying email records in an account holder's email records list 210. Although specific direct and indirect associations are shown, the electronic receipt system may have additional or alternative associations without departing from the scope of the present disclosure.

For example, the account holder may be prompted to enter authentication information 204, such as a user identifier or password corresponding to authentication information stored in the secure database 104, to verify that a user of the user device is the account holder. The profile may also include an email identifier 206, such as a username selected by the account holder. The username may be used as the local part of an email address that the account holder may use to transmit electronic receipts to the common inbox 112 for retrieval by the electronic receipt system 102. The username may be stored in the secure database 104 as an email identifier 206 and associated with the account holder and accounts held by the account holder as described in FIG. 2.

In block 502, the electronic receipt system 102 determines whether the account holder already has a profile established and stored in the secure database 104. In some aspects, the electronic receipt system 102 may use authentication information to identify the account holder and locate information associated with the account holder in the secure database 104. In block 504, subsequent to determining that a profile is associated with the account holder in the secure database 104, the electronic receipt system may retrieve the username included in the profile from the transaction. In block 506, the electronic receipt system 102 displays the unique email address using the username retrieved from the profile in the secure database 104 as the local part of the email address.

In block 508, subsequent to a determining that there is no profile information associated with the account holder in the secure database 104, the electronic receipt system 102 generates a user interface to receive a username from the account holder. In some aspects, the user interface may be generated and displayed on a display unit 414 of the user device 106. The user interface may include an input option to allow the account holder to enter a username that may be used as a local part of the email address and stored as an email identifier 206 in the secure database 104. In some aspects, the username may be required to be different from usernames selected by other account holders to ensure that the email address is unique to the account holder.

FIG. 6 is an example of a user interface 600 for receiving a username for the unique email address of FIG. 5 according to some aspects of the present disclosure. In some aspects, the user interface 600 may be generated by the electronic receipt system 102. In other aspects, the user interface 600 may be generated by the client engine 406 stored in the memory device 402 of the user device 106 of FIG. 4. The user interface 600 may be displayed on the display unit 414 of the user device 106 and includes an input option 602 in which the account holder may enter a username to serve as the local part of the email address. The account holder may enter the username using the keyboard 410 of the user device 106 of FIG. 4. The user interface 600 displays the domain part 604 of the email address to illustrate what the account holder's email address will be if the username is accepted by the electronic receipt system 102. The account holder may select the selection option 606 labeled “Save” to transmit the username entered into the selection from the user device 106 to the electronic receipt system 102 via the network 108.

Returning to FIG. 5, in block 510, the electronic receipt system 102 generates a profile and a unique email address using the username entered into the input option 602 of the user interface 600 of FIG. 6 as the local part of the email address. In some aspects, prior to generating the profile, the electronic receipt system 102 may compare the username entered by the account holder with all of the usernames associated with profiles of other account holders in the authentication information 204 of the secure database 104 to determine whether the username entered by the account holder is unique. One the profile is generated, the unique email address or the username used as the local part of the email address or both, may be stored as authentication information 204 in the secure database 104 and associated with the account holder.

FIG. 7 is flow chart of a process for linking an electronic receipt to a transaction record according to some aspects of the present disclosure. The process is described with respect to the network environment 100 of FIG. 1 and the electronic receipt system 102 of FIG. 3, though other implementations are possible without departing from the scope of the present disclosure.

In block 700, the electronic receipt system 102 may retrieve an email message from the common inbox 112 of the email system 110. In some aspects, the common inbox 112 may include all email messages transmitted to email addresses having the same domain-name, despite having different local parts. For example, the common inbox 112 may include an email message routed to the email address user1@bank.com and an email message routed to the email address user2@bank.com since both email addresses include the domain part “bank.com.” The electronic receipt system 102 may retrieve all email messages in the email address and sort them with the appropriate account holder using the local part of the email address associated with the email message.

In block 702, the electronic receipt system 102 identifies the account holder using the local part of the email address associated with the email message. In some aspects, the electronic receipt system 102 may compare the local part of the address with a list or array of usernames stored in the secure database 104. The matching username may be associated with a profile including the holder identifier 200, account information 202, or authentication information 204 corresponding to the account holder to identify the account holder as the intended recipient of the email message.

In block 704, the electronic receipt system 102 extracts receipt content and metadata from the email message. In some aspects, the server engine 306 may include text-identifying program code or instructions to cause the processing device 300 to identify the metadata and the receipt content. In some aspects, the metadata may include information corresponding to the routing information included in the email message. For example, the metadata may include the “From” information corresponding to the sender of the email message, the “Date” information corresponding to a timestamp of when the email message was sent by the sender or received in the common inbox 112 of the email system 110. In some aspects, the metadata may also include the “Subject” of the email message. In some aspects, the receipt content may include the body of the email message. In some aspects, the body of the email message may include an electronic receipt in text. In other aspects, the body of the email message may include an electronic receipt as an image. In additional and alternative aspects, the receipt content may include an attachment to the email message. The server engine 306 may include program code or instructions to cause the processing device 300 to determine whether an attachment is included in the email address or to determine whether text is included in the body of the email address. The server engine 306 may cause the processing device to extract the metadata and the receipt content from the email message and store them as files or objects in the secure database 104.

FIG. 8 is an example of an email message 800 including an electronic receipt according to aspects of the present disclosure. The receipt content 802 may include the electronic receipt in the body of the email message 800. In some aspects, the electronic receipt may be an image embedded in the body of the email message 800. In other aspects, the electronic receipt may be text in the body of the email message 800. The electronic receipt includes details corresponding to a transaction between the account holder and a sender. The email message 800 also includes metadata 804. The metadata 804 includes sender information corresponding to the sender of the email message 800 (e.g., “Super Store—Store Receipts <custserv@superstore.com>.” The metadata 804 also includes at least the date that the email message 800 was received by the common inbox 112 of the email system 110.

Returning to FIG. 7, the electronic receipt system 102 generates an electronic document using the receipt content 802 extracted from the email message 800 of FIG. 8. In some aspects, the server engine 306 may determine the format of the receipt content 802 (e.g., image, text, etc.) and may convert the receipt content 802 to a standard format that may be accessible from different user devices via the network. In some aspects, the server engine 306 may include known adapter instructions or program code to perform the conversion. In some examples, the format may be compatible with document formats configured to be displayed in a web browser. In some aspects, the format may include a portable document formation (PDF″). In other aspects, the format may include other formats, including but not limited to, a Microsoft® Word® binary file format or XML document format, a log file, an OpenDocument text format, or a rich text format.

In block 708, the electronic receipt system 102 determines if there is a transaction record corresponding to the electronic receipt in the receipt content. In some aspects, the server engine 306 may include a matching algorithm for matching the metadata extracted from the email message to information included in the transaction records stored in the secure database 104 and associated with the account holder. For example, the matching algorithm may include instructions for comparing all or a portion of the alphanumeric characters of the sender of the email message in the metadata with a transaction record having a third party merchant to a transaction having the same characters. The match between the metadata and the transaction record may be confirmed or alternatively performed using metadata information from the “Date” line of the email message compared with a timestamp of a transaction record. For example, the transaction record may include a timestamp corresponding to the date or time that the merchant submitted a request for funds from the account of the account holder subsequent the account holder initiating the transaction using a payment card associated with the account. The matching algorithm may compare the date metadata with the transaction record timestamp to determine whether the corresponding times are within an acceptable range to determine a match.

In additional and alternative aspects, the electronic receipt system 102 may match the electronic receipt to the transaction record using the receipt content. For example, the server engine 306 may include code for deciphering text from the receipt content to determine a transaction amount (e.g., $95.01 for the receipt content 802 of FIG. 8). The matching algorithm may match the electronic receipt to a transaction record having the same amount, or may use the amount to confirm a previous match based on the metadata.

In block 710, subsequent to identifying a corresponding transaction record to the electronic receipt, the electronic receipt system 102 links an email record corresponding to the email message to the transaction record. In some aspects, the email record may include the electronic document generated by the electronic receipt system 102 and including the receipt content. In additional aspects, the email record may also include the extracted metadata and the extracted receipt content separate from the generated electronic document.

In block 712, the electronic receipt system 102 may store the email record in the secure database 104. The electronic receipt system 102 may store the email record in an email records list 210 in the secure database 104. In some aspects, the email records list 210 may include all email records corresponding to email messages routed to the common inbox 112 and addressed to the unique email address of the account holder. In some aspects, blocks 710 and 712 may be performed simultaneously where the electronic receipt data stores a transaction ID in the secure database 104 with the email record as a pointer to link the email record to the stored transaction record associated with the transaction ID. The email records list 210 may include email records linked to secure records in the transaction information 208 as described in block 710 and may include email records determined by the electronic receipt system 102 not to correspond to a secure record.

FIG. 9 is a flowchart of a process for displaying an electronic document linked to a transaction record according to an aspect of the present disclosure.

In block 900, the electronic receipt system 102 authenticates an account holder to view a transaction record stored in the secure database 104. In some aspects, the secure database 104 or another database accessible to the electronic receipt system 102 may include authentication information 204 corresponding to the account holder, such as a user identifier, a password, a social security number, and account number, a PIN, or other identifier. The account holder may be required to transmit the authentication information from the user device 106 to the electronic receipt system 102 via the network 108 (e.g., through a user interface displayed on the display unit 414 of the user device 106 of FIG. 4). The electronic receipt system 102 may receive the authentication information from the user device 106 and compare it to authentication information 204 stored in the secure database 104 to verify that the account holder is authorized to view secure information related to the account associated with the authentication information 204.

In block 902, the electronic receipt system 102 receives a request to view the transaction record. In some aspects, the request may be received from the user device 106 via the network 108 as a signal corresponding to the request. In some aspects, the request may be generated by the user device 106 in response to a selection of a selection option on a user interface generated by the electronic receipt system 102 or the user device 106 via the client engine 406 of FIG. 4. For example, a user interface may include multiple transaction records corresponding to transactions depositing or withdrawing funds from the account of the account holder. The transaction records may include a selection option to generate the signal corresponding to the request to view the transaction record.

In block 904, the electronic receipt system 102 determines if the transaction record has an electronic document 212 linked to the transaction record including receipt content corresponding to an electronic receipt of the transaction. In some aspects, this determination is made in response to the request to view the secure record of the transaction information 208. In other aspects, this determination may be made prior to the account holder selecting to view the transaction record. Using the example where the request is received via a selection option on a user interface including a list of transaction records, the electronic receipt system 102 may determine whether an electronic document is attached to each of the transaction records included in the list subsequent to authenticating the account holder to view the transaction records.

The electronic receipt system 102 may determine whether an electronic document is linked to the transaction record by determining whether there is a pointer or other link included in the secure database 104 in one or both of the locations where the transaction record and the electronic document are stored. For example, the server engine 306 may cause the processing device 300 to identify a transaction ID pointer corresponding to the transaction record that is associated with the electronic document in the secure database 104.

In block 906, subsequent to the electronic receipt system 102 determining that an electronic document is linked to the transaction record selected by the account holder, the electronic receipt system 102 displays information from the transaction record on a user interface.
